起電流時間より短くなるよう設定される。(Example) The present invention will be explained based on the drawings as an example. 1 is a power supply, 2 is a relay 3 connected to this power supply 1.
With the coil 2, the contact 4 is switched once by excitation of the coil 2. 5 is a relay drive switch connected in series to the relay coil 2, specifically using a transistor,
An operation signal is applied to the control terminal B. Therefore, this switch 5 controls the current of the relay coil 2 by turning on and releasing the operation signal. 6 is a diode connected in parallel with the relay coil 2 in the opposite direction;
The back electromotive flow is made to flow for a certain amount of time. The drawings of the embodiments show an example of application to a sequencer in which several relays 6, switches 5, and diodes 6 are connected in parallel. Reference numeral 7 denotes an oscillation circuit interposed between the power supply 1 and the relay coil 2, which outputs an on/off signal. Reference numeral 8 denotes a timing switch for on/off signals of this oscillation circuit 7, which is a transistor. The timing is set so that the relay 6 completes its operation during the ON signal output time η, and the time during the OFF signal output time 1 is shorter than the time during which the back electromotive current passes through the diode 6 and the relay coil 2.

れ、リレー接点4が動作する。(3) (Operation) Next, we will explain the operation of the RAID drive circuit explained in this book.
In FIG. 1, when an operation signal is applied to the relay drive switch 5, the switch 5 is turned on, and the flow goes from the switch 1 to the switch 8.1 of the oscillation circuit 7, and from the coil 2 to the switch 5. Relay contact 4 operates.
係る際に於て、上記発振1路7のオン、オフ信号はその
スイッチ8によって第2図の如く出力する。In this case, the ON/OFF signal of the oscillation 1 path 7 is outputted by the switch 8 as shown in FIG.

イル2は逆起電流かダイオード6を介して流れると共に
接点4を前述の1作状態に維持させる。Subsequently, when the switch 8 of the oscillation circuit 7 is turned off, 1. Since the supply of the source 1 is stopped, the relay coil 2 allows the back electromotive current to flow through the diode 6 and maintains the contact 4 in the above-mentioned 1-operation state.

振回銘7のオフ時間−中は消費電力が亀となる。The off time T2 of the oscillation circuit 7 is shorter than the time during which this back electromotive current is flowing, so the relay 2 continues its operation by the next off signal. Power consumption is low during the off time of this generation (4) 7.

ない効果がある。Of course, if the drive switch 5 is turned off, the relay will stop operating regardless of the output of the oscillator circuit. Connect this relay coil 2 in parallel to the back electromotive force of the coil 2, and connect a diode 6 that allows the current to flow. Since the time during which the back electromotive current of the coil 2 flows through the diode 6 is made longer than during the off signal time, the operation of the relay during the off time of the oscillation circuit 7 can be maintained by the back electromotive current of the coil. Therefore, the power consumption of the relay is only during the ON signal output time of the oscillation circuit, and the relay is not limited to a special type such as a latching relay as in the past.
